QUESTION 70How are I/O timeout and Safety I/O timeout calculated?

A. An I/O connection will timeout based on the lower of 4x RPI or 100ms. Safety I/O timeout is calculated as 4xRPI.B. An I/O connection will timeout based on the lower of 3x RPI or 100ms. Safety I/O timeout is calculated as 3xRPI.C. An I/O connection will timeout based on the lower of 4x RPI or 150ms. Safety I/O timeout is calculated as 2xRPI.D. An I/O connection will timeout based on the lower of 3x RPI or 150ms. Safety I/O timeout is calculated as 3xRPI.

Answer: A

QUESTION 71Refer to the exhibit. CCNA.com has the industrial network shown in the exhibit. All switches are configured as layer 2 switches and are using VLAN 1 as their management VLAN.Each VLAN 1 interface has been assigned the correct IP address.What is the purpose of assigning a default gateway to SW-C switch?

A. allows connectivity between the VLAN 1 interface on SW-C and other devices in the network.B. allows connectivity between Host A and other devices in the network.C. allows connectivity between Host B and other devices in the network.D. allows the switch to pass traffic between Host A and Host B

Answer: A

QUESTION 76Refer to the exhibit. What are three traffic and interconnection requirements for the devices in the exhibit? (Choose three.)

A. The EtherNet/IP drive connections are in a high-voltage area and need protection from electromagnetic noise, so shielded cable that is rated for 600 V is advised.B. EtherNet/IP devices such as the controller, drive, VoIP phone, and IP camera should be in the same VLAN.C. CIP traffic has the highest bandwidth requirement so it needs the highest QoS setting.D. EtherNet/IP drive traffic has high sensitivity to random drops, latency, and jitter.E. Real-time motion control and VoIP traffic can share the same VLAN with the proper QoS setting.F. IEEE1588 and PTP are important for ensuring real-time synchronization.

QUESTION 77You are a called upon to troubleshoot connectivity problems to a network device on a production floor. You have used ping and traceroute to verify that you cannot connect to the device from the management network. The network is 209.165.202.128/27 and the device has been given the IP address 209.165.202.158 and mask 255.255.255.224. You have verified that you can reach the device with your computer connected to the same switch as the device. What could be the cause of this problem?

A. The device is set to the wrong subnet mask.B. The device is set to the wrong IP address.C. The device has no IP default gateway.D. The device is connected to a switchport in the wrong VLAN.

Answer: C
